I am using radtabstrip in aspx page.and using panel to load control in the tabstrip to avoid all tabs to be loaded everytime.

now, within each tab, i have grids (user controls) with add/edit/delete.

i am able to manage dynamic load of controls but when i click add/edit/delete, nothing happens until i click 3 times. i see its going in to code but only 3rd time it goes to itemdatabound and that time only i can do add/edit/delete. however, once i enter the data save it and then again i add/edit, i can do it with one click only.no need to click multiple times for the same tab. if i change the tab,again i have to click 3 times.

why? and how to fix it?

i am attaching the code as well as video. please help.

[Solved] Change Column Name in HeaderContextMenu

Hi,

I have a RadGrid in my page with "EnableHeaderContextMenu" set to true.

I want to change the texts for the columns in the HeaderContextMenu.

With an older telerik version the code snippet below the function was working, now with the latest Version 2015.2.826.45 it doesn't work anymore.

this.GridView.HeaderContextMenu.ItemClick += this.pContextMenu_ItemClick;

void HeaderContextMenu_PreRender(object sender, EventArgs e)

{

// Correct the column names for Context Menue

Telerik.Web.UI.GridHeaderContextMenu pContextMenue = sender as Telerik.Web.UI.GridHeaderContextMenu;

Telerik.Web.UI.RadMenuItem pColumnsContextMenu = pContextMenue.FindChildByValue<Telerik.Web.UI.RadMenuItem>("ColumnsContainer", true);

foreach (Telerik.Web.UI.RadMenuItem pItem in pColumnsContextMenu.Items)

{

pItem.Text = _Regex.Replace(pItem.Text, String.Empty);

}

Kindly help us in solving this issue.

Regards,

Miriam

Unable to remove date in RadDatePicker

In IE 10 & 11, I am seeing an issue when trying to remove dates from a group of RadDatePicker controls. When I remove the values from multiple controls and submit, a dropdown list is visible for the last control selected, for about one second. When I go back to that particular record, the value is still persisted in that same last control I touched. IE 9 does not exhibit this behavior. Neither does Chrome or Firefox. Our Telerik.Web.UI.dll version is 2010.2.826.35.

Dynamic RadFilter

Hello,
I am initializing the RadFIlter component from Server side. After initializing, I am loading the collection list into the component. In the front end, whenever I am clicking on the item of the list, it works fine. There is a refresh interval timeout (5 seconds). After every 5 seconds, I am loading the values from the database on the front end grid.
So whenever I click on any Radfilter items after 5 seconds refresh interval, the error window appears which says "index was out of range. must be nonnegative and less than the size of the collection List". Within the 5 seconds interval, it works fine. It seems the values which I am loading on the server side are getting lost.
I am performing the following steps;



1. On the page initialization, I am creating the Rad FIlter Component.
 this.ComplexFilter = new RadFilter()
                    {
                        ID = "ComplexFilter",
                           AllowFilterOnBlur = true,
                          ShowApplyButton = false,
                          Skin = "Vista",
                          EnableViewState = false
                                           
                    };
this.ComplexFilter.ItemCommand += this.ComplexFilter_OnItemCommand;
this.ComplexFilterPanel.ContentTemplateContainer.Controls.Add(this.ComplexFilter);
fieldEditor.FieldName = column.JsName; // column is the list of items. This I am doing for every column list item.
fieldEditor.DisplayName = column.Name;
 fieldEditor.DataType = column.Type;
this.ComplexFilter.FieldEditors.Add(fieldEditor);
 
var rootGroup = this.Settings.ComplexFilter_Expression;
 if (rootGroup != null)
                {

                     foreach (var expression in rootGroup.Expressions)
                    {
                        this.ComplexFilter.RootGroup.AddExpression(expression);
                    }
                } 
                this.ComplexFilter.PreRender += this.ComplexFilter_OnPreRender;

            if (this.Settings.ComplexFilter_Visible)

                this.Settings.ComplexFilter_Expression = this.ComplexFilter.RootGroup;
 
                newComplexFilterSql = this.Settings.ComplexFilter_Sql = this.Settings.ComplexFilter_Expression.ToWhere(this.TablesTable).ToString();

                newComplexFilterSql = String.Empty;
            } 
            this.ComplexFilter_ReloadData(previousComplexFilterSql, newComplexFilterSql); 
            ComplexFilter.RecreateControl(); 
        }
 
  2. After every 5 seconds Refresh timeout, I am checking for the complex filter saved settings. But due to the null value of ComplexFilter_Expression, settings could not be fetched from the database.
   if (this.ComplexFilter_Visible && this.ComplexFilter_Expression != null)
            {
                where &= this.ComplexFilter_Expression.GetDBWhere(table, joins, out saveSettings); 
            }
            else
            {
                saveSettings = false;
            }

I request to the Telerik expertise, to tell me what I am doing wrong. Why the Telerik object is getting lost due the front end refresh time interval.

BachEditing Row to Row Value don't stay if not focused

Hi Kevin, i need your help quickly about a similar problem :

http://www.telerik.com/forums/itemdatabound-even-in-batch-edit-mode-of-rad-grid

The comboBox works with static WebMethod enableLoadOnDemand=true, autopostback=false option under Radgrid BatchEdit in Row Edit mode.
When I add a new row with the Edit mode (EditItemTemplate > RadComboBox), I select a value in second line RadComboxBox and close editMode : the first ItemTemplate takes the value of the second newly input.

The this a real problem

Scenario Step 1 :

Scenario Step 2 :

Scenario Step 3 :

Scenario Step 4 : the first field red line value should be 71886 but automatically change by 147244 ??

Can you give me some alternative or give me an issue for this problem .

RadGrid Data Bind at client side using PageMethod

Dear All

I created a page method that return the result data source in json string format to bind the RadGrid:

[WebMethod]

public static string GetRows(int from, int len)

{

DataTable dt = MyEntity_BL.GetData();

//convert DataTable into Json string

System.Web.Script.Serialization.JavaScriptSerializer serializer = new System.Web.Script.Serialization.JavaScriptSerializer();

List<Dictionary<string, object>> rows = new List<Dictionary<string, object>>();

Dictionary<string, object> row = null;

foreach (DataRow dr in dt.Rows)

{

row = new Dictionary<string, object>();

foreach (DataColumn col in dt.Columns)

{

row.Add(col.ColumnName, dr[col]);

}

rows.Add(row);

}

return serializer.Serialize(rows);

}

and then i call the page method at client side at user button click:

function btnShowClientClick(clickedButton) {

PageMethods.GetRows(0, 0, Succsess);

}

function Succsess(result) {

var masterTable = $find("<%= grd.ClientID %>").get_masterTableView();

masterTable.set_dataSource(result);

masterTable.rebind();

}

The problem is that there no action done on the RadGrid ??
It doesn't bind any data!

Is there something miss ?

Thanks

Using onserverclick in PagerTamplate to export Grid to CSV

I am using a RadGrid element and need to export CSV data from it. When I place a link outside of the RadGrid element, the export works fine:

<telerik:RadGrid ID="myGrid" runat="server" EnableViewState="false">

etc...

Now when I place that same link within the PagerTemplate, it no longer works and I get a javascript popup error.

<telerik:RadGrid ID="myGrid" runat="server" EnableViewState="false">

<MasterTableView

And the export method..

protected void Export_CSV_Click(object sender, System.EventArgs e)

{

myGrid.MasterTableView.ExportToCSV();

}

How would I get this button working from within the PagerTemplate?
